ours is 100+, and we definitely have nothing like that! then again, we're on high ground/rock out of the water table.

that said, i'm not sure exactly what we're seeing there. looks like bad spalling and then some exploratory demo (the diagonal cuts, circular holes at the top?). the exposed rebar can't be the result of an actual failure.

It almost looks like the new, replacement rebar. That would help explain the rather large holes in the wall (caused by removing the old, rusted / damaged rebar). That's often what happens on these types of jobs - the old steel has to be completely removed until you are back to good steel. Then new steel is installed, bonding coats applied, and new concrete installed.
